Appetude Rates the Dishes Rather than the Restaurant

Appetude lets foodies rate dishes rather than restaurants as a whole. The free app displays a restaurant's entire menu -- even unrated dishes -- so reviewers can dispense "yums" and write comments. Eventually, Appetude will allow users to share reviews via social media tools such as Facebook and Twitter.
